Diagnostics of fuel tanks

Like other technical devices, tanks go through several stages of inspection before and directly during operation. The first stage is an inspection during production. Then a scheduled diagnosis of fuel tanks is carried out.

In total, there may be several types of diagnostics, let’s start with partial diagnostics (without decommissioning the tanks), which includes:

• analysis of technical documentation;
• inspection of tanks;
• control (visual and measuring) of walls, roofs, outer edges of bottoms;
• ultrasonic thickness measurement of roof walls, outer edges of bottoms;
• ultrasonic control of welding seams of walls;
• acoustic emission inspection of walls and floors;
• geodetic measurements of tank bodies and protective embankments;
• examination of the external anti-corrosion coating of housings;
• control calculations of tank structures;
• industrial safety examination regarding the obtained results of partial diagnostics.

In addition to the listed operations, full diagnostics of tanks (with decommissioning of tanks) includes:

• control (visual and measuring) of the pontoon;
• ultrasonic thickness measurement of the pontoon;
• ultrasonic control of welding seams of bottoms;
• control of the tightness of floating roofs (pontoons) and bottoms using the vacuum method;
• mechanical tests of metal and determination of its chemical composition;
  radiographic control;
• examination of the entire anti-corrosion coating of the housings;
• acoustic emission control of walls during hydraulic tests;
• examination of foundations and foundations of tanks;
• industrial safety examination based on the obtained results of full diagnostics of the capacity.

Technological pipelines are also subject to technical diagnosis.
